This project focused on planning and implementing an electrical and control system for a water reservoir in Rehovot (central Israel) which collects and stores surface runoff from heavy rain. The project's primary goal was to regulate water flow efficiently, based on demand and reservoir levels. The system includes sensors for monitoring water levels, flow meters for tracking water output, and electrically controlled pumps for managing flow. A PLC (programmable logic controller) was used to automate the process, ensuring consistent operation and quick response to changing conditions; in case of PLC failure, bypass circuits take over to automate the process. An HMI (human-machine interface) was also developed for real-time monitoring and control. This solution aimed to improve water management, reduce energy consumption, and ensure reliable operation under various scenarios.

This project presented an advanced electrical system design for a factory specializing in prestressed hollow concrete slabs. The goal was to design a strong, efficient, and safe electrical network tailored to the needs of the factory, ready for implementation and complying with the Electricity Law regulations. The electrical system design involved planning and selection of electrical panels, cable selection, lighting systems, voltage drop and short-circuit current calculations, along with an integrated backup system incorporating emergency generators and renewable energy via solar panels. During the planning, emphasis was placed on safety measures, electric shock protection, and power factor improvement strategies. This project supports the operational excellence of the factory with forward- thinking engineering practices.
